Mantle Bridge: Who Pays for Gas on the Destination Chain?

A bridge moves tokens between networks, but the destination wallet still needs that network’s gas token to spend them. With a Mantle Bridge transfer, the wallet submitting each transaction pays its gas; the bridge does not generally add a usable gas balance to the tokens it delivers.

Plan for gas on both sides, because a successful transfer can leave the destination funds temporarily unusable.

Who pays gas when bridging to Mantle?

The wallet that sends the Ethereum deposit pays Ethereum gas, usually in ETH. If the token needs approval first, that approval is a separate Ethereum transaction with its own fee; the deposit then costs gas too.

The arriving balance does not normally include native MNT for later Mantle transactions. You need MNT in the destination wallet to send the tokens onward, swap them, or approve them for an app. A token balance and a gas balance serve different jobs.

For a fuller walkthrough of the transfer and its checks, see mantle bridge. If you are sending to another person’s address, that person will generally need MNT to use the funds after arrival, unless the route explicitly offers a gas or refuel feature.

Who pays gas when withdrawing from Mantle?

The wallet initiating a withdrawal pays Mantle gas in native MNT. When the withdrawal becomes ready to claim on Ethereum, the wallet submitting that separate claim pays Ethereum gas in ETH.

That means a withdrawal can require two different gas balances at different stages. The claim fee is not automatically taken from the ETH or tokens waiting to be released: the claiming wallet needs ETH available when it sends the transaction.

If the receiving Ethereum address differs from the wallet that starts the withdrawal, check who can submit the claim and who will fund its gas. The asset’s destination and the transaction signer’s gas balance are separate parts of the process.

How much destination gas should you keep?

There is no fixed amount that fits every transfer. Gas changes with network conditions and with the actions you plan to take, so check the wallet’s current estimate for each transaction and keep a reserve for the next step.

• For an Ethereum deposit, budget ETH for any token approval and for the deposit itself.
• For using funds on Mantle, hold native MNT in the wallet that will send, swap, or approve.
• For a Mantle withdrawal, budget MNT to start it and ETH in the claiming wallet for the later Ethereum transaction.
• If a bridge offers refuel or gas delivery, check whether it is included, what it costs, and which destination address receives it.

Do not assume that an MNT token balance on Ethereum will pay fees on Mantle; gas must be available on the network where the transaction runs. For a self-transfer, that often means arranging the destination gas separately before or after the bridge. For a transfer to someone else, agree who will provide it before sending.

The practical rule is simple: identify the wallet that will sign each step, then fund it with that chain’s gas token. Treat the bridge transfer and the first action with the arriving funds as separate transactions with separate costs.
